本文实例讲述了WordPress分类与标签等存档页完成置顶的办法。分享给大家供大家参考。详细剖析如下：

在wordpress中默许能置顶文章就是只有首页了,假如咱们心愿分类/标签等存档页也能置顶文章咱们需求二次开发.

如今参考wp-includes/query.php中首页置顶的代码,略微修正一下,能够让分类页、标签页、作者页和日期页等存档页面也能像首页一样在顶部显示其范畴内的置顶文章,把上面的代码放到以后主题下的functions.php中就能够了.

add_filter('the_posts',  'putStickyOnTop' );  
function putStickyOnTop( $posts ) {  
  if(is_home() || !is_main_query() || !is_archive())  
    return $posts;  
      
  global $wp_query;  
  $sticky_posts = get_option('sticky_posts');  
    
  if ( $wp_query->query_vars['paged'] <= 1 && is_array($sticky_posts) && !emptyempty($sticky_posts) && !get_query_var('ignore_sticky_posts') ) {        $stickies1 = get_posts( array( 'post__in' => $sticky_posts ) );  
    foreach ( $stickies1 as $sticky_post1 ) {  
      // 判别以后能否分类页   
      if($wp_query->is_category == 1 && !has_category($wp_query->query_vars['cat'], $sticky_post1->ID)) {  
        // 去除不属于本分类的文章  
        $offset1 = array_search($sticky_post1->ID, $sticky_posts);  
        unset( $sticky_posts[$offset1] );  
      }  
      if($wp_query->is_tag == 1 && has_tag($wp_query->query_vars['tag'], $sticky_post1->ID)) {  
        // 去除不属于本标签的文章  
        $offset1 = array_search($sticky_post1->ID, $sticky_posts);  
        unset( $sticky_posts[$offset1] );  
      }  
      if($wp_query->is_year == 1 && date_i18n('Y', strtotime($sticky_post1->post_date))!=$wp_query->query['m']) {  
        // 去除不属于本年份的文章  
        $offset1 = array_search($sticky_post1->ID, $sticky_posts);  
        unset( $sticky_posts[$offset1] );  
      }  
      if($wp_query->is_month == 1 && date_i18n('Ym', strtotime($sticky_post1->post_date))!=$wp_query->query['m']) {  
        // 去除不属于本月份的文章  
        $offset1 = array_search($sticky_post1->ID, $sticky_posts);  
        unset( $sticky_posts[$offset1] );  
      }  
      if($wp_query->is_day == 1 && date_i18n('Ymd', strtotime($sticky_post1->post_date))!=$wp_query->query['m']) {  
        // 去除不属于本日期的文章  
        $offset1 = array_search($sticky_post1->ID, $sticky_posts);  
        unset( $sticky_posts[$offset1] );  
      }  
      if($wp_query->is_author == 1 && $sticky_post1->post_author != $wp_query->query_vars['author']) {  
        // 去除不属于本作者的文章  
        $offset1 = array_search($sticky_post1->ID, $sticky_posts);  
        unset( $sticky_posts[$offset1] );  
      }  
    }  
    
    $num_posts = count($posts);  
    $sticky_offset = 0;  
    // Loop over posts and relocate stickies to the front.  
    for ( $i = 0; $i < $num_posts; $i++ ) {  
      if ( in_array($posts[$i]->ID, $sticky_posts) ) {  
        $sticky_post = $posts[$i];  
        // Remove sticky from current position  
        array_splice($posts, $i, 1);  
        // Move to front, after other stickies  
        array_splice($posts, $sticky_offset, 0, array($sticky_post));  
        // Increment the sticky offset. The next sticky will be placed at this offset.  
        $sticky_offset++;  
        // Remove post from sticky posts array  
        $offset = array_search($sticky_post->ID, $sticky_posts);  
        unset( $sticky_posts[$offset] );  
      }  
    }  
    // If any posts have been excluded specifically, Ignore those that are sticky.  
    if ( !emptyempty($sticky_posts) && !emptyempty($wp_query->query_vars['post__not_in'] ) )  
      $sticky_posts = array_diff($sticky_posts, $wp_query->query_vars['post__not_in']);  
    // Fetch sticky posts that weren't in the query results  
    if ( !emptyempty($sticky_posts) ) {  
      $stickies = get_posts( array(  
        'post__in' => $sticky_posts,  
        'post_type' => $wp_query->query_vars['post_type'],  
        'post_status' => 'publish',  
        'nopaging' => true  
      ) );  
      foreach ( $stickies as $sticky_post ) {  
        array_splice( $posts, $sticky_offset, 0, array( $sticky_post ) );  
        $sticky_offset++;  
      }  
    }  
  }  
    
  return $posts;  
}

1、假如你想让存档页也都显示全副置顶文章,那么就删掉11-43行的代码；

2、假如不想在某分类页显示置顶文章,将第 3 行的

if(   
//改成：  
// abc是分类称号  
if ( is_category( 'abc' ) ||

if(   
//改成：  
// abc是标签称号  
if ( is_tag( 'abc' ) ||

if(  
//改成：  
 // abc是作者昵称  
if ( is_author( 'abc' ) ||

代码如下:

|| !is_main_query()

置顶款式:假如你想给置顶文章增加款式,将以下代码增加到functions.php中,会给置顶文章增加一个名为 sticky 的class,详细的css代码,再自行自定义：

add_filter('post_class',  'addStickyClass' ,10,3 );  
function addStickyClass( $classes, $class, $post_id ){  
  if( is_sticky() && is_category() && !isset( $classes['sticky'] ) ){  
    $classes[] = 'sticky';  
  }  
  return $classes;  
}
